This example demonstrates a world map rendered with D3.js using the geoPolyhedralWaterman projection from d3-geo-projection. It shows country boundaries from a TopoJSON world atlas dataset, overlaid with red rectangles positioned at two specific latitude/longitude coordinates, though the rectangles do not use the map projection and remain in screen space. The visualization uses d3.geoPath to generate SVG paths for countries and a sphere outline, with d3.geoGraticule available for reference lines. The code imports feature from topojson to convert TopoJSON data into GeoJSON features for rendering.

Let's make a map with D3.js!

The example demonstrates how to create a world map visualization using D3.js, rendering geographic features as SVG elements. It shows country boundaries and a styled ocean sphere, with countries colored light green and outlined with subtle black strokes. The code loads GeoJSON data via `d3.json` from the world-atlas TopoJSON dataset, converts it using the TopoJSON client library, and projects the map with `d3.geoPath` and a geographic projection. The visualization includes a blue sphere background and depends on D3 v5 and the `topojson` library for data processing.

Let's make a map with D3.js

This example renders a world map using D3.js and TopoJSON. It shows the entire globe as a blue sphere with light green countries, using the `geoEqualEarth` projection and `geoPath` to generate SVG paths. The map draws country boundaries from the `world-atlas` dataset loaded via `json()`, demonstrating a simple choropleth-style base map with subtle stroke effects.

Let's make a map with D3.js!

This example displays a world map of countries rendered as light green SVG paths on a blue spherical globe projection. It uses D3 v5’s `d3.geoNaturalEarth1` projection and `d3.geoPath` to draw country boundaries, with TopoJSON’s `feature` method converting the world-atlas 110m dataset into GeoJSON. The code appends a background sphere path, then loads country data from a remote URL and enters it into the SVG. Country strokes are semi-transparent black, with no interactivity or labels.

Let's make a map with D3.js

This example renders a world map using D3.js and TopoJSON, applying the natural Earth projection via `d3.geoNaturalEarth1` and drawing country boundaries with `d3.geoPath`. The SVG shows a blue sphere outline and light green countries with subtle black strokes. It loads country geometries from the world-atlas 110m TopoJSON dataset and converts them to GeoJSON using TopoJSON’s `feature` function. The code appends paths for the sphere and each country, demonstrating a straightforward choropleth-free geographic visualization.

Lets make a map with D3.js

This example shows a world map rendered as an SVG using D3.js v5 and TopoJSON. It loads world country boundaries from the world-atlas package and converts the TopoJSON to GeoJSON with the `feature` function, then draws the map with `d3.geoPath`. The visualization is minimal, with a 960-by-500 viewport and hidden page margins, and demonstrates the basic pipeline of fetching geographic data and projecting it onto the screen.

Let's make a map with D3.js!

This example demonstrates how to construct a world map using D3.js, rendering individual countries as SVG paths with light green fills over a blue spherical background. The visualization loads geographic data from the world-atlas TopoJSON dataset and applies a geoAzimuthalEquidistant projection, clipped to a rectangular viewport using geoClipRectangle. It relies on d3.geoPath to generate the SVG paths and topojson.feature to convert the TopoJSON topology into GeoJSON features for display.

Let's make a map with D3.js!

This example creates a world map rendered as SVG using D3 v5 and TopoJSON. It loads world country boundaries from the World Atlas TopoJSON dataset, projects them with the `geoNaturalEarth1` projection, and draws each country as a filled path using `d3.geoPath`. A blue sphere background is added first, with countries shown in light green and outlined with subtle black strokes. The map displays the entire globe with country shapes accurately projected.

Let's make a map with D3.js

This example displays a world map rendered as an SVG, with countries filled in green against a dark blue spherical backdrop. It fetches country boundaries from a TopoJSON file via the world-atlas dataset, then projects them using the Hufnagel projection from `d3-geo-projection`. The code builds paths with `d3.geoPath` and `d3.json`, styling the sphere and landmasses through CSS classes. It relies on D3 v5, TopoJSON’s `feature` method, and demonstrates a compact, data-driven mapping workflow.
